Who called from 2136230000

I use google voice and added them to my nuisance caller list...straight to voicemail for them.

I just change my number to an unlisted number. I am paying extra NOT to receive unwanted phone calls and now I receve calls from this number.........HELP???

It's Time Warner Cable's call back system. I received an automated message from this # and it was basically a survey asking how the service was.

Time Warner is not an option in my area, and I am not a subscriber.  Maybe they are a large company handling automated surveys for several companies.  What little information I do have leads me to believe that they are mostly automated with no actual people involved in the calls.

I don't subscribe to Time Warner Cable. In fact, it's not even an option where I live. I just got a call from that number though... I'm guessing that's not it.
